Can We Install a New Graphics Card to an All-In-One Desktop with Integrated Graphics?

The short answer is it depends on several factors. If an all-in-one desktop has Thunderbolt 3, you might be able to use an external card. Otherwise, it is unlikely due to the lack of expansion slots in all-in-ones. This guide will help you determine if an upgrade is feasible and what steps are involved.

Upgrade Possibilities

All-in-one computers are often seen as space-saving alternatives to desktops with a separate monitor. As such, they lack the flexibility of traditional desktops when it comes to expandability. However, if you already have a Thunderbolt 3 connection, you can use an external GPU (eGPU). But otherwise, you may need to consider other options, such as building a proper PC.

Requirements for Installing a Discrete GPU

If you're keen on upgrading to a discrete GPU, here are the essential requirements you need to meet:

PCI-E x16 Slot: Your motherboard must have an unoccupied PCI-E x16 physical slot to install the new graphics card. Power Supply Unit (PSU): Ensure that your power supply can provide the required wattage, typically between 100-280 watts, via dedicated 12V rails. The exact power requirements vary depending on the GPU type. For example, a GT 1030 does not require additional power connections, whereas a RTX 2080 Ti might need dual 8-pin connectors. Free Space and Ventilation: Make sure your computer case has enough free space to accommodate the new GPU and proper ventilation to avoid overheating.

Disabling Integrated Graphics

When using a discrete GPU, it is often recommended to disable the integrated graphics and set the BIOS to initialize the display from the PCI-E slot connected to the GPU. This can be done by entering the BIOS settings and adjusting the appropriate options to prioritize the discrete GPU over the integrated one.

BIOS Settings for GPU Initialization

Typically, you will need to change a BIOS setting to disable the integrated graphics. However, this is not always necessary, and it depends on your specific setup. Here's a step-by-step guide:

Access the BIOS via the manufacturer's settings parameter during the boot-up process. Find the option related to display initialization or GPU priority. Select the option to initialize the display from the external GPU or the PCI-E slot connected to the new GPU. Save and exit the BIOS settings to apply the changes.

External GPUs (EGPU)

If your all-in-one desktop does not have a PCI-E slot or the power requirements are too high, an External GPU (eGPU) can be a viable solution. An eGPU is a self-contained external computer that provides powerful graphics processing capabilities. Some popular brands include Razer Core, Elgato Extreme, and Apple Redux.

However, eGPUs are typically more expensive and not everyone needs this level of performance. If you are on a desktop PC with integrated graphics, you can often install a new GPU as long as your PC has a PCI-e slot and sufficient power supply.

Buying the Right GPU

When choosing a new graphics card, consider not just the price but also the performance you need. While it might seem tempting to stick with integrated graphics or a low-end GPU for cost-saving reasons, a dedicated GPU can significantly improve gaming, graphics rendering, and general performance. Some examples of affordable yet powerful GPUs include:

NVIDIA GT 1030 AMD Radeon RX 550 NVIDIA GeForce GTX 1650

Ultimately, the decision to upgrade your graphics card comes down to your specific needs and the budget you are willing to allocate. Consider factors such as gaming performance, software requirements, and overall system performance before making the decision.

Conclusion

While it may not be straightforward to upgrade the graphics card in an all-in-one desktop, it is possible under certain conditions. This guide has covered the requirements, steps, and considerations to help you determine if upgrading is worth the effort. Whether you choose to invest in a dedicated GPU, an external GPU, or stick with integrated graphics, make an informed decision that aligns with your needs and budget.
